摘要： Adaptive contrast enhancement of image data is provided. In one embodiment a method for adaptive contrast enhancement includes receiving image data for a first frame, determining a pixel distribution for at least one color space component of the first frame based on luminance values of the pixels in the at least one color space and calculating an average picture level in the at least one color space based on the pixel distribution. The method additionally includes adjusting a look-up table (LUT) associated with the pixel distribution based on the average picture level, converting luminance values of the pixels in the first frame in the at least one color space based on the LUT to generate an enhanced image frame and outputting the enhanced image frame.

摘要： A circuit for recovering the data encoded in several VBI channels without requiring a large number of gates. An analog to digital converter (ADC) and a clock and data recovery circuit may be associated with one of several possible channels. ADC over samples each VBI channel, and clock and data recovery circuit determines which subset of the over samples represent the encoded data by examining the over sampled samples. The selected subset may be stored in a shared memory and a equalizer may process the subset of samples of all channels to perform tasks such as deghosting. Due to the shared equalizer, the number of required gates may be minimized.

摘要： An electronic identification tag, usually in very small size, responds to a reader with an identification code unique to the object to which the tag is attached. The stand-alone device responds to a reader signal by storing energy received from the signal, then using the stored energy to generate another signal that is encoded with identification information. In operation, a reader generates RF energy which can reach a multiplicity of such tags over a distance of several meters. The system minimizes power requirements for the tag by minimizing intelligence in the IC. Use of a transmit frequency which is different from the reader's power frequency reduces interference between the power pulse and information pulse, eliminates the need for filters and enables the multiplied clock reference frequency as the transmit carrier frequency.
